Product Name
Leister 113.874 4mm (0.16 in) Round Screw-On Speed Welding Nozzle (without tacking tip)
Brief Description
This is a precision-engineered, screw-on nozzle designed for hot-air speed welding of round plastic rods, specifically 4mm (0.16 inch) in diameter, and is supplied without a tacking tip. It serves as an essential accessory for various Leister hot-air welding tools, facilitating efficient and consistent plastic joining.
Popular Applications & Uses
- Draw welding applications.- Welding plastic plates together.- Repairing polyethylene tanks and cracks in plastic components.- Repairing car bumpers.- Pipe and tube welding.- Plastic tank fabrication.- Installation of resilient flooring coverings.- General plastic repairs.
Industries that Commonly Use It
- Plastic Fabrication- Construction/Building Services (e.g., roofing, flooring, geomembranes)- Marine (for boat construction and repair)- Automotive Service/Repair (for plastic component repairs)- Pool/Spa/Plumbing (for pipe and tank welding/repair)- General Manufacturing (for plastic components and systems)- Energy (for geomembrane sealing in landfill projects)- Tarp, Fabric, Awning Manufacturing (for welding plastic membranes)
Special and Unique Features
- Features a secure screw-on connection for reliable attachment to compatible tools.- Specifically designed for speed welding using 4mm round welding rods.- Constructed from precision-engineered stainless steel for durability and performance.- Lacks a tacking tip, which is ideal for specific welding techniques and finishes.- Compatible with a wide range of Leister hot-air tools, including WELDING PEN S/R, DIODE, TRIAC, HOT JET S, and LABOR S models.
Key Properties
- Nozzle Diameter: 4mm (0.16 inches).- Nozzle Connection: M14 screw connection.- Material: Hardened steel / precision engineered stainless steel.- Temperature Tolerance: Capable of withstanding high temperatures, typically up to 800°C for hardened steel nozzles.- Suitable Welding Rod: Designed for use with 4mm round welding rods.
Surface Compatibility
This nozzle is compatible with various thermoplastics commonly used in welding applications, including:- Polyvinyl Chloride (PVC)- Polypropylene (PP)- Polyethylene (PE), including HDPE, LDPE, LLDPE- Thermoplastic Polyolefin (TPO)- Acrylonitrile Butadiene Styrene (ABS)- Ethylene Chlorotrifluoroethylene (ECTFE)- Polyamide (PA)- Polycarbonate (PC)- Chlorinated Polyvinyl Chloride (PVC-C)- Unplasticized Polyvinyl Chloride (PVC-U)- Polyvinylidene Fluoride (PVDF)
Known backups / known substitutes
- Other Leister round speed welding nozzles available in different diameters (e.g., 3mm, 5mm) for varied rod sizes.- Leister round drawing nozzles that include a tacking tip (e.g., model 113.399) for applications requiring initial material positioning.- Other specialized Leister nozzles, such as wide slot nozzles, tubular nozzles, or triangular speed welding nozzles, are used for different joint geometries or larger material sections.- Nozzle adapters (e.g., Leister 143.833) can convert push-fit tools to accept screw-on nozzles, expanding compatibility.
Comparison Note
The Leister 113.874 4mm Round Screw-On Speed Welding Nozzle is specifically engineered for precision and efficiency in welding 4mm round plastic rods, particularly in draw welding applications where a tacking tip is not desired. Its screw-on design ensures a highly secure and stable connection to the hot-air tool, which is crucial for consistent weld quality. This distinguishes it from push-fit nozzles or wider slot nozzles, which are typically used for different types of plastic joints or larger material sections, highlighting its specialized role in achieving clean, strong round rod welds.
